Sea levels may rise FIVE feet this century

The world’s sea levels could rise twice as high this century as U.N. climate scientists have predicted, according to researchers who looked at what happened more than 100,000 years ago, the last time Earth got this hot.

Experts working on the U.N.’s Intergovernmental Panel on Climate Change have suggested a maximum 21st century sea level rise — a key effect of global climate change — of about 32 inches.

But researchers said in a study appearing on Sunday in the journal Nature Geoscience that the maximum could be twice that, or 64 inches.

They made the estimate by looking at the so-called interglacial period, some 124,000 to 119,000 years ago, when Earth’s climate was warmer than it is now due to a different configuration of the planet’s orbit around the sun.

…..” Back then, Greenland was 5.4 to 9 degrees Fahrenheit warmer than now — which is similar to the warming period expected in the next 50 to 100 years, Rohling said.
